Several invoices in single PDF (for print)..

Hello experts,

I have this issue.. I am generating invoices massively through WebDynpro Java, we need those invoices in their print format, so far I can put one invoice document per PDF, but it is non practical for the volume of generated invoices to print one by one..

I need to create several invoices in one PDF, with their corresponding header and items. So that the user can send to print lots of documents at a time.

I hope you guys can guide me trhough this issue, I can't figure it out how to have One header per page with their Items..

I repeat, I have successfully created one full invoice in the PDF (header + items), now I need to create more than one page, every invoice in its corresponding page.
